Reading Processor Variant and Fusemap from the console

yates — Mon, 07 Aug 2017 17:07:52 GMT

We are using the DART 6UL board from Varascite and their Yocto-generated 4.1.15 distribution. I have the following questions:

Is there a way to read the processor variant (G0, G1, etc.), e.g., from the /proc file system (from the console)?
How do you read the fuse map from the console? We want to read fuse map location 0x430, bits 21:20, "TAMPER_PIN_DISABLE[1:0]" (from the imx6 applications processor reference manual).

Namely I want to find out if the tamper inputs have been fused so that they cannot be used as GPIO outputs.

Thanks in advance for any pointers.

Hi Randy

seems one can read the fuse map with: cat /sys/fsl_otp/
